する投球練習機。 A rotary tube with a peripheral surface facing the strike number display window and with the number of strikes indicated in sections is installed in a box that has an opening corresponding to the strike zone and a strike number display window on the front, and a ratchet is attached to the rotation axis of the rotary tube. Attach a rotating pulley wrapped around a rope that urges and rotates the ratchet wheel in one direction by the wheel and a heavy peg, and a rewinding pulley wrapped around a rope that rotates the ratchet wheel in the opposite direction. , a stopper that is engaged with the ratchet wheel by a spring to prevent the ratchet wheel from rotating, and a stopper that is installed in the ejection groove for balls thrown into the box from the front opening and that comes into contact with the balls traveling in the ejection groove. A pitching practice machine characterized by being provided with a flap that tilts when the flap is tilted, and an engagement release means that releases the engagement of the stopper against a spring by the tilting of the flap.
